Motor Configuration
The motor configuration menu allows you to adjust the behavior of the stepper motor and provide the
stacking controller with the information necessary to calculate stack depth.
Use the up and down buttons to move between parameters. Use the enter button to toggle parameters
on and off, and digits 0-9 to modify the values of numeric parameters.
Half-step (on/off): if on (recommended), the motor is driven in half-step mode, which is more precise,
generates less vibration, uses less power, and produces less heat. The downside of half-stepping is that
it has less torque, but this should not be a concern for most applications.
Reverse (on/off): if you want the motor to move in the opposite direction when operating it from the
position menu, toggle this parameter.
St/rev: set this parameter to the number of full steps in one revolution of your stepper motor. To
determine the proper value, divide 360° by your motor's rated °/step. A 1.8 °/step motor will give a
value of 200.
µm/rev: set this parameter to the number of micrometers that your stage advances over one revolution
of the stepper motor. This value is used to calculate the stack depth readout in the position and stack
menus, but does not otherwise change the behavior of the stacking controller.
Max RPM: this parameter sets the maximum speed of the stepper motor. Experiment with different
speeds to determine what works best for you. 120 RPM should work well for many standard stepper
motors. Higher speeds are more likely to cause missed steps, stalling, and reduced torque.
Relax motor (on/off): If on (recommended), the motor is braked when not in use. This reduces heat, but
also reduces holding torque.
